Applied Aerospace & Defense, Inc. (AADX) — IPO Dossier

AADX is a 100% primary raise that exists to repair its own balance sheet. The company receives roughly $604.3 million in net proceeds — at the $20.00 IPO price — and directs nearly all of it to debt repayment ($548.2M to term loans, $56.1M to the revolver), taking a $1.02 billion debt load down by more than half. Sponsor Greenbriar keeps 81% control and sells zero shares. What public investors are buying is the de-lever — and a $1.06 billion defense and aerospace backlog priced into the recovery.

Demand read

AADX presents the BDI engine with a distinctive signal mix. On the bull side: a bulge-bracket-led ten-firm syndicate (Morgan Stanley, Jefferies, BofA, RBC, Guggenheim, Baird, Stifel, plus the Wolfe-Nomura alliance and Academy as defense co-manager), a $1.06B contract backlog supporting forward demand, FY2025 revenue growth of 25% (51% pro-forma including CBI), adjusted EBITDA margin expanding to 23.6%, and a clean Big Four (EY) audit with no material-weakness disclosure. On the caution side: net losses in every reported period, a Q1 2026 swing to an operating loss of $2.8M, ~$1.02B of debt against $233.8M of equity, an IPO whose stated purpose is to repair the balance sheet rather than fund growth, an 81% controlled-company structure, and a roll-up still digesting four acquisitions in 18 months. BDI calibrates these competing signals into an institutional-grade demand read at READY; the dossier reader should treat AADX as a real defense-and-space platform whose investment case is partially conditional on the deleveraging actually completing as priced. Bellipo's BDI methodology (patent pending) is designed to surface exactly this kind of tension between distribution strength and balance-sheet condition, rather than collapse it into a single number prematurely.

The Bellipo take

This is a balance-sheet IPO, framed as a defense-and-space growth story. Both are real. AADX is a Greenbriar roll-up — Applied Aerospace Structures (founded 1954) combined with Rotor Topco, ICEL, NeXolve, and CBI between 2024 and 2026 — now bringing aggregated revenue, a $1.06 billion contract backlog, and a 23.6% adjusted EBITDA margin to market. The growth case is the defense and space mission-critical components business: subsystems for launch, defense aviation, and C5ISR programs. The caution case is everything that lives below operating income. AADX has posted a net loss in every period shown, and Q1 2026 swung to an operating loss of $2.8M from +$11.9M a year earlier — direction matters. Interest expense alone ate $72.8M in FY2025 against $58.9M of operating income, which is exactly why the de-lever IPO exists. A bulge-bracket-led ten-bank syndicate (Morgan Stanley lead) and a real backlog argue for institutional support; an 81% controlled-company structure, integration risk on a four-acquisition roll-up still being digested, and customer concentration in U.S. government contracts argue for caution on the public-holder experience. Read the leverage as carefully as the backlog.
